Ryan Shumway, 30, of McAlester, turned himself in at the McIntosh County District attorney's office, two days after the body of Gary McInnich, 55, was recovered from Lake Eufaula, troopers said.

Shumway was driving the white and dark color ski boat that was traveling about 30 mph and struck two boats that were anchored about 400 yards north of Sherwood Point. The anchored boats were displaying proper lighting, but the ski boat struck the bow of one boat, went airborne and landed on the second boat.

The ski boat left the scene, troopers said.

McInnich, of Oklahoma City, was found about 7 p.m. Saturday in 17 feet of water about a mile east of Eufaula Cove. He had been missing since the accident about 10:10 p.m. Thursday, troopers said.
